Multiple Products on Sentinel License Manager

I would like to confirm that you have to configure two servers to host licenses of two products. The Sentinel Admin Control Center uses the terminology "Products" plural and test install on my personal PC lists two Products so clearly the technology is designed to support multiple product licenses from a single server.

And yet we have been given two separate keys for our seats of TBC Complete and TBC Advanced with the direction that each must be installed on a separate server. This doesn't make sense to me as every network license manager I have ever seen is able to handle multiple products from the same company and even from different companies.
